PROFILE
Gleb Smirnov
Worked on the gear-tech/gear repository, delivering core backend and blockchain enhancements over eight months. Focused on modernizing development workflows, refactoring runtime components, and improving reliability through robust error handling and database compatibility safeguards. Leveraged Rust, Nix, and Shell scripting to streamline build automation, optimize memory usage, and enforce data structure constraints. Introduced custom thread pools for transaction processing, enhanced API and CLI usability, and improved onboarding by refining the development environment. Addressed security and performance by limiting transaction payload sizes and optimizing storage for blockchain state. The work emphasized maintainability, efficient resource management, and scalable system architecture throughout.

Dec 1, 2025Month: 2025-12 | Gear Tech – gear repository: Delivered SDK and Program Management Enhancements by consolidating gclient into gsdk, adding benchmarking support, and refining weight calculations for create_program and upload_program. Fixed Gear Program Creation Reliability Bug to prevent account death by validating balance against existential deposit. Strengthened CI/CD and packaging to stabilize builds and tooling, including free disk space optimization in CI, addition of cargo-haraki to the development environment, and updated Nix pins. Benchmarking and stability refinements include initial payload support, correct MAX_PAYLOAD_LEN usage, and weight-signature fixes. Overall impact: more reliable program lifecycle, safer resource handling, faster and more predictable builds, and clearer performance signals for optimization.
